My listing in booking.com showing that its not available

I seldom check on booking.com to have a look at my own listing. I thought of checking on the rates for similar homestay at the area of my listing but i found out that when i search for my own listing in booking.com for my property, its showing that this homestay is not available for the date that i chose. I tried to change the date a few times but it is still the same. So I would like to know is it that booking.com is trying to control the search results so that other homestays or listings will get a equal chance of getting sales? i also found out that actually the price that i put for my property are too low compare to others , so is this an issue. Of course after looking at other listing, Im more than happy to raise the price for my listing. Please advise who should i contact regarding this issue. Thanks
